The IETF and the IANA (parent to the RIR's) has already set
aside address space for exactly this use.

Please READ  RFC-1918 on Private IP Space.
Your choices are:

>There are 33,000 registered business in New Mexico (my home

>If we say that the average state has 15,000 businesses that 
>should have a /24, that would create a routing table around

>That doesn't scale well.  Memory requirements far exceed current

>So, we should just leave all of these addresses _reserved_ 
>forever?  Or only available to the fortune100?  All because 
>routers are slow?  Make /24s available to small businesses and 
>router vendors will be forced to make it scale well. 

The addresses are not "reserved" forever.  If you look at the 
allocation trends you will see that many /8's have been moved
from the IANA_RESERVED status to being allocated to a RIR.
Those RIR's then have allocated them to providers.

Your comment about "will be forced to make it scale well" is like
saying.  If you want a VW-Bug to go faster, put a larger engine in
it.  There is a point where you can no longer put a larger engine
in the car.  e.g it does scale well beyond a 351.

>>Most small business don't even have 15 hosts, let alone 254 of them. 

>Which companies did you poll?  My numbers would be significantly 
>different.  But I do not have facts, so I will not publish them. 

2000 of 2800 members of the Greater ABQ Chamber of Commerce report
less than 15 FTE's or are in a business where their FTE's do not
need access to computer (eg retail sales, etc)

If you don't have facts, then I don't see how your numbers will
be significantly different. :)

>>Bottom line is that the RIR's need to operate based on what works 
>>well for the various users of the space.  Allocating /24's to every 
>>business that comes along is not in the best interest of the 
>>global internet. 

>Obviously I disagree.  Providers will just have to upgrade their 
>routers.  ;) 

Can't upgrade what doesn't exist.  

Who will pay for the 6100 ISP's in North America to "just upgrade"
their routers???  Not even talking about the large providers.

>So what if we run out of IP addresses.  If I can`t get one because it

Running out and reserved is apples and oranges.

No the reserved space is not in the routing table.  Only the 
announced and currently used space is in the table.
